Extraordinary performance in a ruggedly portable, high power, tilt-back package, the KB12 Kickback bass combo features the added muscle of a 500 watt Class D power amp and a premium 12” HyDrive speaker.

The HyDrive Design
The KB12's 12" HyDrive speaker features Hartke’s patented paper/aluminum hybrid cone technology for an exceptional blend of warmth and transient attack that can't be attained by traditional all-paper bass speakers. The use of rare earth neodymium magnets provides lightweight portability without sacrificing any of the legendary Hartke tone.

In addition to sitting upright, the KB12 can be placed in the "kickback" position for better on-stage monitoring and clarity. The KB12 also features a headphone output for practice and a balanced XLR direct output to the mixer for live performance. With all new high power amps and HyDrive speakers, the Hartke KB12, and its big brother the KB15, have re-defined the standard for professional bass combos.

What started as a simple string and pedal sales catalog has grown exponentially over the past thirty years. The early days were a time where catalogs didn't have much of a presence in the industry, but what began as a college dorm room operation grew rapidly. In 1986 we moved to a full product offering and 64-page catalog, which over the years has grown to 162 pages. Join the AMS family and get your free catalog now!
